<p>This element encodes raw video into a VP9 stream.</p>
<a class="ulink" href="http://www.webmproject.org" target="_top">VP9</a> is a royalty-free
<p>video codec maintained by <a class="ulink" href="http://www.google.com/" target="_top">Google
</a>. It's the successor of On2 VP3, which was the base of the
Theora video codec.</p>
<p>To control the quality of the encoding, the <span class="type">“target-bitrate”</span>,
<span class="type">“min-quantizer”</span>, <span class="type">“max-quantizer”</span> or <span class="type">“cq-level”</span>
properties can be used. Which one is used depends on the mode selected by
the <span class="type">“end-usage”</span> property.
See <a class="ulink" href="http://www.webmproject.org/docs/encoder-parameters/" target="_top">Encoder Parameters</a>
for explanation, examples for useful encoding parameters and more details
